i Application led November 6, 191]..l Serial No. 658,814. v,

Be it known that we, CHARLES T. WEST- LAKE and CHARLES F. Fianna,citizens' of the United States, residing at St. Louis, vMissouri, haveinvented a certain new andvuse` ful Improvement in Railway-CarUnderframes, of which the following is a full, clear, andexactdescription, such as will enable others skilled in the artto whichit appertains to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1 is a plan view of a. car underframe of our improvedconstruction. Fig. '2 is an enlarged cross-section taken approximatelyon the line 2-2 of Fig. l. Fig. 3 is an enlarged cross-section takenapproximately on the line w of Fig. '1. Fig. 4 is and enlargedcross-section taken approximately on the line 4 4 of Fig. 1.

Our invention relates generally to the under-fiaunes of railwaypassenger cars and more particularly to that portion of the under-framewhich comprises the double r1`he principal objects of our invention are,to. combine in a single integral casting, the double body bolster, theend sill and the greater part of the buffer beam, to unite one lend ofthe end sill with the correspondi1;0r end of the buffer beam by anintegral rail, to form-one end of the buffer bealn separate from themain body portion thereof and to attafch the san to the main body ofsaidbeam ait the side of the step opening. To construct the end sill so.that it will support the lower ends of` the end posts attached to saidend sill and to provide a ,simple under-frame construction whichcombines several essential parts and4 which can be easily andcheaplymanufactured, and combines lightness of weight with great strength andrigidity, therebyreadily resisting suche` shocksk and strains as may bereceived in service.

To the above purposes.v our invention cono sists in certain novelfeatures of construction and arrangement of parts hereinafter more fullydescribed and claimed.

Referring by numerals to the accompanybolster which' is ofv theusualform and construction `and 'formed integral with one end thereof andproject-ing forwardly therefrom 'i is a pair of side rails 2 and acenter beam 3 which form the platform proper, and formed integral withthe ends of these rails and beam is a plate or rail 4 preferably Z shapein cross sectionas shown, or of any desirable shape having an outwardlyprojecting bottom flange 4a and an upwardly projecting flange 4b.Thislast mentioned flange 4b is in direct vertical alinement with thevertically disposed web of the. rail 4. lThis plate or rail 4 performsthe function of an end sill andthe 'bottom flange 4a forms a support forthe end posts 10. The elevation of the plate 4 is limited by lthe fixedlocation of the floor level and the 'degree to which the bottom flangemay bellowered is likewise limited and in order to obtain sufing surfacefor the lower portions ofthe end posts, thev upwardly projeetingiange 4"is provided.

The frame of the platform for the passenger landing comprises a seriesof longitudinally disposed webs 5 which are formed integral with andprojecting forwardly 'from the central portion of the plate 4 andbetween these webs are formed pockets 6 for bufling gear, (not shown).

7 designates the buffer beam which is of the usual box-shape and asshown, this beam is formed integral with the outer ends of the platformwebs 5. A buffer beam cud piece or extension 7ra is formed integral withone end of the main body of the buffer beam and uniting the end portionof this end or extension 7a and the adjacent end of `the plate 4, is anintegral rail 8 which is jnactically a continuation of the side railThis rail S is offset relative to the corresponding side rail 2 in orderto permit a .corner post 9 to be applied to the corner of the platformatthe point where the plate 4 joins the side rail 2. V K., lo designatesend posts of any desired `shape in cross-section the lower ends of whichposts rest upon the horizontal Harige 'la of the 'end sill and thelaterally projecting flanges of said end posts are fixed to the verticalweb of the end-sill by means of rivet-fl or in any suitable manner.

l 1 designates commercially rolled members..

preferably in the formA of angles which form the bottom chords of theside walls of the ear-body and these. members are connect- ,110'

led to the side rails 2 and to the side rails of the double body bolsterby means of suitable 'metal brackets 12. O n the open or step sidebuffer beam, and at this point, said member is connected to saidextension by means of an angle bracket 18. The lower edges ot' themetallic side plates 14- ot the ear-body are fixed in any suitablemanner to the vertical Webs of the members 11. i

Formed throu Vh the top plate ot' the main body or" the butlier beam 7and at the ends thereoi: are openings 15 adapted to receive the lowerends of the vestibule posts 16, which as shown, are preferably in theform of I beams.

17 designates a removable end section which forms the ,end portion ofthe butler beamat the side 'of the step opening and this endy section isattached directly to the corresponding end of the butler beam 7 lbymeans of rivets as shown in Fig. 3 or in any suitable manner.

It 4will be noted that in our improved construction that the entireplatform and the main portion of the butler beam are formed integralwith the double body bolster and that the end of the integral butterbeam is united with the corresponding end ot the end sill by an integralbeam and this arrangement provides a very strong, rigid constructionwhich will withstand such strains and shocks as it may be subjected toin service.

By making the end of the butler beam ot the step side of the platformremovable, said end when broken, can readily be replaced by a new endone without discarding the entire undert'rame.

lt will be readily understood that minor changes in the size, form andconstruction ot the various parts ot' our improved undertrame can bereadily made and substituted for those herein shown and describedwithoutdeparting from vthe spirit of our invention, the scope ot whichis set forth in the appended claims.
